	Dear Erik,
thanks for help

I used command without mpirun, because such opportuniny is described in
paper manual p. 114
Also syntax for using mpirun described there doesn't work on my double
processor computer. What works is:

mpirun -np 2 mdrun_mpi -np 2 -s pokus.tpr -o pokus.trr -c pokus.gro -v -N 2 

But probably also some 'nicer' syntax is possible.

Maybe for benephit of other users page 114 in paper manual should be

	Best regards
